FOLDER ATTACHMENT FOR HEMMERS.

. Specification of Letters Patent.

Patented March 12, 1907.

Application filed October 24,1905. Serial No. 28 1.145.

' used with hennners.

' The object of the invention. is to provide an attachment for such machines affording means for folding the material before presenting the same to the l1emmer,'tl1e general purpose being to dispense with hand operators who fold the goods in the same man ner.

. The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims.

Figure-1 is a perspective view showing a portion of a sewing.1nachine to which my invention has been applied, certain parts being broken away. Fig. 2 is a plan view of the folder; Fig. 3 is an end elevation of the folder.- Fig. 4 isa vertical cross-section throu h a part of the folder, taken on theline 4 4 of ig. 2 and on an enlarged scale. Fig. 5 is a longitudinal section through the same part of the folder a plane substantially at right angles to the line 4 '4. Fig. 6 is a cross-section on the line ,6 6 of Fig. 2 and upon an enlarged scale; and Fig.7 is a fragmentary plan showing a portion of thefolder as represented injFigp2, and showing the guide in an adjusted position, exposinga slot in the-plate which facilitates the passing of the goods to the folder."

Referring more particularly to the parts, 1

represents the table of a sewing-machines upon which-the usual base-plate 2 is attached, This base-plate is provided with the usual mechanism. which is not shown, the same being for thepur pose of operating a needle-bar 3. Adjacent to this needle-bara: henuucr or heinnung mechanism 4 is attached in the usual manner, said hemmer comprisingm tongue 5, which projectsbodily from the table 1, and. rcceiving-lips-(i and Z, disposed on opposite sides of the said tongue, as indicated.-

The body S of the improved folder attachincn't consists of a substantially horizontal plat e suitably.supported on a shelf 9 by One extremity of the plate 8 is formed with a scroll or roll 11', the same increasing toward the edge 12, which is adjacent to the sewingrnachine and beginning substantially at the edge 13, which is remote therefrom, asindicatedmost clearlyin Figs. 2 and 3. Near the ed e 12 and near the overhanging edge .14 of t 's scroll I attach an adjustable guideplate 15, the same having an elongated shank 16 with a slot 17 therein, through which a clamping-bolt 18 passes. The construction means of adjustable brackets 10, as shown. 2

of this guide-plate is shown very clearly 1n Fig. 4. It is substantially T-shaped in plan, as indicated in Fig. 2, its body being disposed longitudinally of the edge 11 and fitted at its outer edge with a downwardly-bent flange 19, as indicated most clearly in Fig. 4.

Preferably atthe edge 20. of the plate 8, which lies opposite the edge 11, I-attach a holder 21, the same consisting of an elongated arm 22, provided with a laterally-disposed foot 23, which is attached rigidly to the plate, as indicated. At its outer extremity the arm 22 is provided with a longitudinallydisposed slot :24, at which point a tongue 25 is attached by means of suitable bolts 26, passing through the aforesaid slots. tongue 25 is attached to a base-plate or body plate 27 disposed therebeneath and through which theolts 26 also pass. The base- .plate 27 projects in-the same direction as the arm 22, so as to constitute an extension thereof. Thetongue 25 extends, however, beyond the extremity of the plate 27 and is preferably curved or bowed upwardly, as shown. Through the body of the tongue 25 an adjusting-bolt 28 passes upwardly, the lower extremity of the said bolt being at tached to theextremity of the body-plate 27. A threaded-thumb-nut 29 is attached on the extremity of this bolt above the tongue, and

a spring 30 is arranged between the tongue and the body-plate 27, which tends to-incline the tongue upwardly,. as will be readily understood. Evidently byv adjusting the thumb-nut29'the tongue 25 may be elevated or depressed, as-desired. The extremity of the tongue 25 is bent over, so as to form a curved shoe 31, as indicatedmost clearly in Fig. 6, and'the curvature of this shoe conforms substantially to the curvature of the scroll 11, near which the shoe is held. The

outer face of this shoe 31 is preferably covered with a facing 32 of canvas or similar material.

,wardly toward its middle, as indicated most clearly in Fig. 5. *-A,djace11t to the plate 8 an inclined chute or slide 35 is provided, the edge whereof restsagainst, the edge 13 of the plate8. The chute 35 is attached adjustably to the u per edgeof- 'a'rail 37 of a suitable feed-talo e 36, which is adapted to receive the goods before passing through the machine. The end'38 of the table, remote from the sewing-machine, is preferably provided .with an inclined shelf 39, hinged thereto, as shown at40. The upper face of the chute v is preferably provided with a covering ofcane lvas or similar material, and the edge'35 of .the chute .is-slightly curved so as to fit the curve of the roll lland so that the folding'of thegoods is initiated in a manner to be herei inafterzdescribed as the material passes on the folder-plate.

It is to be understood that in using this attachment' a considerable length of the goods I will befed continuously to the machine, so

that-a continuous hemis made 'onits edge. After-both edges are treated in this way the goods maybe cut up into suitable lengths to form 'handkerchiefs or similar articles and the cut edges-will be hemmed afterward.

The goods will be fed to the folder, as indifloated i'n-Fig. 2, where a ortion of the incoming material is indicate in dotted lines at 4-1.

From an inspection of this figure it will be seen that the right edge 42 of the material conforms itself. as it advances to theshape of the scroll 11. When the material arrives at the guide 15, the raw edge {12 will'lie substantiallyagainst theinner side of the flange 19 of the guide, as indicated most clearly in Fig.

4. ,Thehemmeraongue 5 being placed just beneath this guide 15 and under the scroll 1 1 I receives the goods, as indicated inlFig; 4.

' goods passes under the same.

The fold .43 of the'goods lies on the u per side of the tongue, while the body 44 'o' the The s ring 33 I operates at this time to hold the b0 y of-the goods up against the under side of thetongue,

as will be readily understood, In this way as-the goods advances to the hemmer itis.

presentedina neat fold. The Width of this foldfis determined by the position of -the guide 15. As indicated inFi 2', the guide is" adapted to make-afoldo mean width.

Evidently if the. guide were moved into an adjusted osition toward" the left the width of thefol fwould be increased.

' The functionaof the tongue 25 is to press the material'by means of the shoe 31- against assists in maintaining the goods in its proper position and alinementas it advances. By means of the thumb-head 29 the degree of pressure at the shoe 31 may be nicely. adjusted, and evidently by reason of theslot 24 the tongue may be adjustedhodily, so as the scroll 11.

of the roll 11 just beneath the guide.15 and in position to take the folded goods asthe operation progresses.

:The spring 33, referred to above, isprefing-strip 15- of canvas or similar material.

I prefer to make one' of the. side. rails'ifl on the table 36 adjustable, and for this purjecting arms 46, provided with slots' 17, which receive clamping-bolts, as shown.

In practice where .the'folder isito' beused prefer to'make the plate8 in sections 8 and 8 rigidly connected along a-transverse line 48. From this arrangement the sections 8 8* may be given any suitable construction signed to that plate.

a longitudinally-disposed slot 19, the purpose of which is-to facilitate the passing of the goods through the folder when the machine is about to beset in operation. Evidently such as a stout pin, can. be inserted-so as to engage the goods and advance thesame longitudinally toward the hemndef; Near the edge 13 on the roll .11 I attach a clip 11, which presents an overhanging lip adapted to. engage the side edge of-the advancing assist in. keeping the material in proper alinement.

While I have described the folder-plate 8 as heingsubstantially, horizontal, I, prefer in practice to arrange it slightly depressed at and this tendency operates to keep the edge of the goods constantly against the flange 19 this way a fold ofconstant widthis maintained as. the sewing 0' era'tion progresses.

Having thus, descri ed my invention, I claim as new and desire to secure by Letters Patent r the entrance to the scroll or roll 11, which In Fig. 2 the relation of the folder with, respect to the hemmer-tongue is very nicely shown. It should appear from this figure that the hemmer-tongue lies under the edge .erably covered on itsupper side with a facpose 'I provide the same with laterally-pro tp'turn .folds varying greatly width I j i by reason of this slot a pointed instrumentp goods. This clip thus operates as a stop to of the guide 15 and against the clip 11. 111

From this arrangement thematerial manifests a f tendency to work slightlyv toward the right,
